A melee weapon you are holding is imbued with deep cold. For the duration, a rime of frost covers the weapon and light vapor rises from it if the temperature of the surrounding area is above freezing. The weapon becomes magical and deals an additional 1d4 cold damage on a successful hit. The spell ends if you cast it again or if you let go of the weapon.

The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
